anyone here ever try using acetone in their gas to see if it will increase gas millage? they say that if you mix 2oz of pure acetone with every 10 gallons of gas you will see a increase in fuel economy and lower emissions. they claim the acetone reduces the surface tension. my brother said he used it in his 86 monte carlo ss and went from 11.9 to 13.5 mpg. hes the only person ive known thats tried this so i wondering if anyone here has and what their results were
